Scientists have identified Earth’s oldest-known impact crater, and in doing so may have solved a mystery about how our planet emerged from one of its most dire periods.

Researchers have determined that the 45-mile-wide (70-km) Yarrabubba crater in Australia formed when an asteroid struck Earth just over 2.2 billion years ago. The collision occurred at a time when the planet was believed to have been encased in ice and the impact may have driven climate warming that led to a global thaw.
